Hand-planted maize, beans, and squash sustained the Mayans for millennia, until their culture collapsed about 1,100 years ago. Some researchers have suggested that the Mayans’ very success in turning forests into farmland led to soil erosion that made farming increasingly difficult and eventually caused their downfall. But a new study of ancient lake sediments has […]
